Usage:
[variables]
cpus = ${f:cpulist_unpack:1,2,3-5}
The 'cpus' will be set to '1,2,3,4,5'. Also the built-in function can take
arbitrary number of arguments which will be concatenated, e.g.:
[variables]
cpus = ${f:cpulist_unpack:1-3,5:6-7,9}
This means two arguments to 'cpulist_unpack' function. The first argument:
'1-3,5' and the second '6-7,9'. The result: '1,2,3,5,6,7,9'.
Also renamed internal function 'unpack_cpulist' to 'cpulist_unpack' to be
more consistent.
